Warfare in Space, Part 3

Image via Wikipedia
Dear Readers,


   This is the third and final in my series on space warfare.  It has been an exciting ride, between conventional warfare in space and inertia-negated warfare, but it's time to bring it to a close with my third and final assumption, one that occurs in many of the time streams I study:


One or both of the belligerents have invented a means of traveling faster than the speed of light.

  I do not mean a vehicle that moves between points A and B while passing all the points in between, because that's going to be lead to all kinds of causality violations.  Rather, I am talking about devices that utilize either teleportation or wormholes to transfer a craft between one point in space and another in faster time than it would take for light to travel between those two points.  Ideally, the transfer would be instant.

   So, how does that affect warfare in space?
